  • the present invention relates to a container of folded blank.
  • the present invention also relates to a method of forming a container from a blank.
  • the present invention also relates to a blank for a container.
  • the present invention may be applied in the field of containers for the storage or the transport of items or materials.
  • the present invention relates to rigid or semirigid containers, having polygonal section, for example boxes, formed by folding or erecting one or more blanks made of paper.
  • the present invention relates to a container for confectionery products such as candies, chewing gums, and the like.
  • Containers and boxes formed from suitably folded blanks made of paper, are known. These containers may be used for confectionery products such as candies, chewing gums, and the like.
  • the containers are used for transporting and protecting the content; in the case of containers formed from blanks made of paper, the capability of protecting the content is lower compared to containers completely made of plastic, such as small cans.
  • containers made of paper are sometimes overwrapped with a plastic film, in particular made of polypropylene, to further protect the content during the shelf life.
  • the Applicant noticed that, when a container is provided from a blank made of paper, the additional coating made of an external plastic film is required, to suitably protect the content.
  • the external plastic film must be removed by the user upon the first opening, and it is therefore an immediately available waste.
  • the user opens a container protected by an external plastic film, (s)he must go to a waste basket into which (s)he has to dispose of the plastic film, once it has been removed.
  • a correct waste sorting requires that said plastic film is disposed of in plastic-waste container, which is not always present in many contexts.
  • the document WO2021002797A1 relates to a packaging container made of cardboard, having a bottom and/or top formed by a bottom and/or upper curled edge, by folding or rolling the bottom end/upper end of the wall of the container's body toward the inside, thereby avoiding the need for plastic components that make the recycling of the packaging container more difficult.
  • the Applicant evaluated that the containers obtained from a blank made of paper or of paperboard do not effectively protect the content during shelf life.
  • container obtained from a blank means a container made of folded paper or paperboard, obtained from one or more flat sheets that are suitably cut and folded to obtain the desired final shape; additional processing may also be provided, such as embossing, gluing, welding, printing, etc.
  • paper or paperboard means a material in sheets, of suitable grammage, composed of raw materials, especially vegetable materials, joined by felting and dried; said material may comprise further materials, for example plastic materials, typically laminated or also dispersed in the material.
  • grammage means the weight of a material referred to a square meter of product containing the material.
  • barrier paperboard means a paper sheet covered with a foil or coating of plastic material, typically of polyethylene (PE). Frequently, barrier paperboards are allowed in paper recycling.
  • PE polyethylene
  • flaps that are at least partially airtight adjoined, being it understood that full airtight or liquid-tight sealing may be achieved in particular embodiments.
  • the Applicant found a solution of container that allows a consumer to transport a content and access it in an immediate and pleasant manner.
  • a container formed from a blank made of paper allows to reduce a use of plastic materials, promoting materials that have a lower environmental impact and/or that are easier to recycle.
  • the invention is directed to a container of folded blank.
  • the container comprises a front panel, a rear panel, a plurality of lateral panels and a bottom wall.
  • the lateral panels are configured to join the front panel and the rear panel on two sides, constituting a perimeter of the container.
  • the bottom wall closes the container at the bottom.
  • the container comprises a lid hinged on the rear panel and closable at the top on the container.
  • the container comprises an upper panel, closing the container at the top below the lid.
  • the upper panel is connected at the top to the front panel and has an access element to the container.
  • the container allows to protect more effectively its content during the shelf life.
  • the lid and the access element allow the consumer to access the content in an immediate and pleasant manner, thereby preserving its freshness over time.
  • the container protects more effectively its content, in particular by providing a package made of paperboard with barrier layers that protect the product on the inside and that are heat-sealing to make sealings that enable elimination of plastic films on the outside of the container.
  • the container according to the present invention achieves a sealed box-shaped body, thereby obtaining a sift-proof box.
  • the invention is directed to a forming method of a container.
  • the forming method provides for folding a blank comprising a front panel, a rear panel and a plurality of lateral panels.
  • the forming method provides for folding a bottom wall of the blank, for closing the container at the bottom.
  • the forming method provides for folding an upper panel of the blank.
  • the upper panel is connected at the top to the front panel so as to close said container at the top.
  • the upper panel has an access element to the container.
  • the forming method provides for folding a lid of the blank.
  • the lid is hinged on the rear panel so as to be above the upper panel.
  • the lid is closable on the container.
  • folding a bottom wall of the blank for closing the container at the bottom may indifferently occur before or after the upper panel and the lid have been formed and closed.
  • the actions corresponding to the forming method are thus to be understood not necessarily carried out in the described order, as long as they are adapted to obtain the final configuration of the container.
  • the invention is directed to a blank.
  • the blank is adapted to be folded for providing a container according to the present invention.

  • the lid comprises shaped flaps that define perimeter walls of the lid.
  • the tear-off closing fastener is adapted to be torn off in an initial opening of the container, and the shaped flaps of the lid are configured to cooperate with the tear-off closing fastener, thereby engaging the lid. In this way, it is possible to effectively close the container after the first opening, thereby preserving the freshness of the content.
  • the upper panel has an extension exceeding a distance between the front panel and the rear panel, so that, when the blank is folded, it is possible to provide an upper panel adapted to close the container at the top in an effective manner.
  • the access element comprises an openable portion of the upper panel to access a content of the container.
  • the access element comprises an openable portion of the upper panel to access a content of the container.
  • the access element is closable at least partially by the lid. In this way, it is possible to preserve the freshness of the content in the best possible way even after the initial opening of the container.

  • the container 100 has the shape of a parallelepiped with very flattened rectangular base and rectilinear edges.
  • the hinged lid 2 is of the flip-top type, preferably with integrated gluing and fastening flaps, although alternative structures are possible.
  • a blank namely a sheet
  • precut and prescored with creases and partial and through cuts of paperboard.
  • said blank made of paper or of paperboard comprises at least one inner layer of a substance acting as a barrier to the inlet of oxygen and steam and at least one inner layer. More preferably, an outer layer of heat-sealing material (for example PLA or PE) is also provided.
  • the final shape of the container determines the drawing of the starting blank, that may be then pre-glued if the structure will allow it (so, with the only presence of linear edges and a development that is divisible into two equal parts) or processed in its spread form and closed in a machine onto three-dimensional shapes if there will be edges with curved lines that do not allow to flatten it after the initial gluing.
  • the container has a structure obtained from a single-piece die-cut object, but it is possible to make it also from a die-cut object made of two or more pieces assembled together.
  • a blank 101 is shown, here depicted in flat configuration and which is adapted to be folded to form the container 100.
  • the blank 101 from which the container 100 is formed, comprises a front panel 3, a rear panel 4 and a plurality of lateral panels 5, which are configured to join the front panel 3 and the rear panel 4 on two sides, so as to constitute a perimeter of the container 100 in the box-shaped body 1.
  • the container 100 has only two lateral panels 5, since the box-shaped body 1 has a rectangular section; if the box-shaped body had a different section, such as hexagonal, octagonal, etc., a higher number of lateral panels would be possible.
  • the plurality of lateral panels 5 further comprises a perimeter closing flap 5b, which is adjoined, in particular glued or welded depending on the applications, to close the box-shaped body 1 of the container 100.
  • the blank 101 comprises further panels adapted to make a bottom wall 6, which closes the container 100 at the bottom.
  • the blank 101 further comprises panels adapted to make the lid 2, closable at the top on the container 100.
  • Said lid 2 is contiguous and hinged on the rear panel 4, in particular at an upper side thereof.
  • the blank 101 further comprises an upper panel 7, which, once the container 100 has formed, is adapted to close the container at the top, thereby creating a volume contained in the box-shaped body 1 below the lid 2.
  • the upper panel 7 is connected at the top to the front panel 3.
  • the upper panel 7 further comprises an access element 8.
  • the access element 8 comprises an openable portion, preferably openable by tearing off, of the upper panel 7.
  • the access element is directly a hole or an aperture, possibly coverable by means of a removable label.
  • the access element 8 thus allows to access a content of the container, to pull out for example a candy, or a chewing gum, or other small confectionery products.
  • the blank 101 comprises a plurality of closing upper tabs 11, connected at the top to the lateral panels 5 and in particular adjoined to the upper panel 7.
  • the blank 101 further comprises a plurality of bottom panels 9 and 10.
  • the bottom panels 9 and 10 are contiguous and continuous with respect to each other, in the sense that they do not have cuts separating their continuity, but they are connected with each other by the continuity of the material.
  • said bottom panels comprise first panels 9 that are folded on themselves in an angled manner so as to collapse on themselves.
  • the bottom panels comprise second panels 10, that are folded and overlapping the first panels 9 and further overlapping each other, having an extension in height slightly higher than half the thickness of the container 100.
  • the panels 9 and 10 constitute a sealed bottom wall.
  • the panels 9 and 10 are connected with each other to form a continuous perimeter, which is then folded to form the bottom wall, similarly to what happens in the gable-top brick-shaped cartons typically used to contain beverages.
  • the bottom panels might have cuts without spaces separating their continuity, and might be folded and glued to form a bottom wall, similarly to what happens in the sift-proof cartons.
  • the bottom panels are preferably folded and welded, inserting a punch inside the partially folded blank and pressing from the outside with a suitable heated mold.
  • the blank 101 is folded to constitute the box-shaped body 1, comprising the front panel 3, the rear panel 4 (not visible in the figure), a plurality of lateral panels 5.
  • the perimeter closing flap 5b (not visible) is adjoined to constitute a closed perimeter of the box-shaped body 1.
  • the bottom wall 6 (not visible) is folded, before or after the lid 2 and the upper panel 7 whose folding and forming will be further described.
  • the bottom wall 6 is closed after closing the lid 2 and the upper panel 7; in this case, it is possible to fill the container with its content, by turning it upside down and filling it from the bottom wall, still open, which will then be the lower part of the container.
  • the invention also provides folding a plurality of closing upper tabs 11, which are connected at the top to the plurality of lateral panels 5.
  • the upper panel 7, which is connected at the top to the front panel 3, is further visible in the figure.
  • the upper panel 7 of the blank 101 is folded, so as to close the container 100 at the top.

  • the closing upper tabs 11, which were previously folded, are adjoined to the upper panel 7, so as to close the container 100 at the top in an effective manner.
  • the closing between the closing upper tabs 11 and the upper panel 7 is made so as to make a substantially closed, sealed, surface.
  • this is obtained through a suitable gluing of the closing upper tabs 11, such as to close up to the corners to make adjoined surfaces that are continuous, without residual passages.
  • Said closing flap 7b is adjoined to the lid 2 through welding or gluing, according to the ways that will be described below, to close the box-shaped body 1 of the container 100 at the top.
  • the upper panel 7 has an extension exceeding a distance between the front panel 3 and the upper panel 4 (not visible), i.e. an extension exceeding the width of the lateral panel 5.
  • the extension of the upper panel 7 is such to bridge an upper gap of the box-shaped body 1 of the container 100, so as to close it at the top in an effective manner.
  • the closing flap 7b is welded or glued to the lid 2, once lifted, so as to close the container 100 at the top.
  • a first area 70 of gluing or welding between the closing flap 7b and the lid 2 is provided, for locally adjoining the upper panel 7 and the corresponding portion of lid 2 to each other.
  • the closing flap 7b further comprises a tear-off closing fastener 7c, which is folded again and adjoined to the upper panel 7. To this end, a second area 71 of gluing between the tear-off closing fastener 7c and the respective portion of upper panel is provided.

  • the lid 2 further comprises a tamper evidence 12, which is adapted to indicate an initial opening of the container 100.
  • a tamper evidence 12 which is adapted to indicate an initial opening of the container 100.
  • additional labels which also indicate tampering, might be used.
  • the lid 2 of the blank 101 is indeed hinged on the rear panel 4 (not visible, on the back of the figure). In this way, the lid 2 is adapted to be above the upper panel 7, thereby making an effective closing. Moreover, the lid 2 is closable on the container, as it will be further described.
  • the previously described tear-off closing flap 7c is adapted to be torn off in an initial opening of the container 100, so as to stay at the upper wall defined by the upper panel 7, such as for example shown in the figure.
  • the shaped flaps 2b and 2c of the lid 2 are configured to be folded and adjoined to each other, to constitute the structure of said lid 2 by defining its perimeter walls.
  • the lid 2 is adapted to cooperate with the tear-off closing fastener 7c that detached from the closing flap 7b upon the first opening of the container. Thanks to the cooperation between the lid 2 and the tear-off closing fastener 7c, it becomes thus possible to close the container 100 many times during its use.
  • the already described access element 8 is thus closable at least partially by the lid 2, thereby providing an effective protection of the content of the container 100.
  • the tamper evidence 12 provided on the lid 2 in the configuration shown in the figure is torn off, thereby indicating that the initial opening has already happened.
  • an openable portion is provided, for example openable by tearing off or removable, even re-attachable if desired.
  • Said openable portion allows the access to a content of the container 100, for example to take out a confectionery product such as a candy or a chewing gum.
  • the openable portion has an opening pre-score to let the product out, which may or may not integrate a repositionable self-adhesive label for an improved protection or more precise handling.
  • the openable portion of the access element 8 is closable at least partially by the lid 2, once it has been folded downward using the hinge connection, and in particular by engaging with the tear-off closing fastener 7c.
  • a container 200 is shown.
  • the container 200 is pyramidal with curved edges, to improve stability or appearance.
  • a blank 201 of the container 200 is shown in a flat configuration.
  • lateral panels 5 and 5c which are configured to join the front panel 3 and the rear panel 4, so as to constitute a perimeter of the container 200 in the box-shaped body 1.
  • the lateral panels 5 and 5c are in a higher number, to constitute a container 200 having a substantially octagonal section with curved edges.
  • a blank according to the present invention is adapted to be folded for providing a container according to the present invention.
  • the blank preferably comprises one or more sheets of paperboard, in particular barrier paperboard. Moreover, the blank is folded according to a forming method according to the present invention.
